The LLC Operating Agreement needs to be drafted in such a manner as to convey certain IRS compliance language that will allow the IRA custodian to accept the LLC as an investment of your IRA.  

From my understanding, this is an acceptable manner for both the IRS and the US Tax Court in terms of substantiation.

Do I have to wait a couple years so I can demonstrate more clearly that I do indeed have a sustainable business model, or does having continuous income whether it's from my own income or from a regular W-2 job count?

Lying is very serious charge for an agent.. it could lead to fruad in the inducement of contract and all other manner of bad things for them.. 

That's just not normal, nor is it sustainable.

Sustainable expense cutting can cut hundreds of thousands of dollars off the amount you need to save and invest for financial independence.   

If you need the money to sustain then the money from buy and hold is slow, it is long term play, so you would then probably want to rehab.

To be sustainable in any market. 

I have a few guys from Tel Aviv that invest with us already in a quite fluid manner.  

Annual maintenance is budgeted in a similar manner.
